Occult Portopulmonary Venous Shunt Leads to Paradoxical Cerebral Embolism After Variceal Embolization

A case in JVIR reports a paradoxical cerebral embolism from an unrecognized portopulmonary venous shunt after gastroesophageal variceal embolization, emphasizing pre-procedural detection of such shunts to avoid this complication.

• Design: Single case report.
• Key finding: The embolic event occurred due to an occult portopulmonary venous shunt that was not identified before the procedure.
• Limitation: Single case limits generalizability; further study needed to determine shunt prevalence and screening strategies.
